Extracted text: Find the standard deviation, s, of sample data summarized in the frequency distribution table below by using the formula below, where x represents the class midpoint, f represents the class frequency, and n represents the total number of sample values. Also, compare the computed standard deviation to the standard deviation obtained from the original list of data values, 11.1. [E(f•x)]-[Z•x]* n(n - 1) Interval 30-39 40-49 50-59 Frequency 2 60-69 70-79 4 1 80-89 90-99 4 13 33 37 Standard deviation= (Round to one decimal place as needed.) %3D Consider a difference of 20% between two values of a standard deviation to be significant. How does this computed value compare with the given standard deviation, 11.1? O A. The computed value is significantly greater than the given value. OB. The computed value is not significantly different from the given value. O C. The computed value is significantly less than the given value. Click to select your answer(s).
